Thanks very much Andrew. I was hoping to be able to plug into the USB port on the pedal as that would enable me to create an add-on option for the user. I'm part of a small team who are designing the pedal (I wrote the Firmware and the Python apps), and the hardware is pretty much finalised so I did...

I am interfacing between an app I've written in Python (that I can run on both Windows and macOS), and a guitar pedal I've been working on, via a USB cable. The app sees the pedal as a serial port e.g. COM4 on Windows, and the computer and pedal communicate using simple text commands, at 57600 baud....

While testing one of the HCMODU0058 1.3" UOLED displays I accidentally discovered that it somehow works without connecting the GND and VCC pins to a power source! I've repeated this with a number of similar 1.3" SH1106-based OLED modules and they all work even if GND and VCC are left unconnected. I ...

Thanks Andrew. I thought I was cracking up for a while LOL!

If I try to display a variable (int or long) which has a zero value, the 0 doesn't appear on the display! For example, adapting the HCuOLED Example code for HCuOLED_Text_Example, the display should show: -101 A zero:0 -101 A zero:0 -123.05 but instead I get: -11 A Zero: -11 A zero: -123.05 i..e no z...

OK so I got it working. I had to install the latest Arduino IDE (1.8.7) over the top of the old version so now everything compiles as it should.

Thanks for you help and maybe this can also help anyone else who may have had a similar problem.

Regards,

Well that didn't work :-( Here's the verbose output after copying Wire to the Arduino IDE 160 libraries folder: Arduino: 1.6.5 (Windows 8.1), Board: "Arduino Uno" Using library HCuOLED in folder: F:\Arduino\libraries\HCuOLED (legacy) Using library SPI in folder: F:\Arduino\libraries\SPI (legacy) F:\...

Thanks for the rapid response Andrew. I checked and found that my Wire library is in an older Arduino IDE installation. I'll try copying it to the Arduino IDE 160 folder but oddly, my own sketches using the Wire library all compile ok, but I'm using #include <Wire.h> within the sketch itself and I d...

Any ideas why I'm getting this compiler error regarding Wire.h? Arduino: 1.6.5 (Windows 8.1), Board: "Arduino Uno" In file included from HCuOLED_Text_Example.ino:42:0: F:\Arduino\libraries\HCuOLED/HCuOLED.h:38:18: fatal error: Wire.h: No such file or directory #include <Wire.h> ^ compilation termina...
